This invention relates to building construction and has special reference to concrete building construction. I

One of the important objects of the present invention is to provide a novel arrangement of molds for molding a building as a single concrete unit.

A second important object of the invention is to provide a novel arrangement of means for molding the outer and inner beams of a building constructed of concrete.

A third important object of the invention is to provide a novel means of molding the floor in such a building.

A fourth important object of the invention is to provide novel means for molding the various parts of a concrete building, which means are adaptable to be arranged for any particular size or shape of building.

A fifth important object of the invention is to provide novel means for so molding the outer and inner beams of a concrete structure and the floors that they are connected together to form a unitary construction.

A sixth important object of the invention is to provide means of this character which can be permanently used, that is to say can be used for one building and then transferred to another, so that there is no loss in material in the molding of the concrete for various buildings.

A seventh important object of the invention is to provide a novel means for molding posts or columns for such a building.

With the above and other objects in View, the invention consists in general of certain novel details of construction and combinations of parts, hereinafter fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims.

In the form of the invention herein shown, in Figure 1 there is provided a construction at each floor which consists of an outer or girdle mold member I0, preferably of channel form. At various intervals within this girdle l0 there must be provided internal mold members capable of molding the girdle beams around the outer part of the floor and also of molding the longitudinal and transverse beams of the structure. Each of the members provided for this purpose consists of a generally rectangular structure ll having telescopic flange members I2, each of which is of rectangular construction and forms an inwardly facing channel so that between each of the general structures II and the girdle Hi there is formed a space 13 for the reception of the cement forming the girdle beams. The several members II are separated, one from another, as shown in Figure 1 so that they are spaced in such manner that cement may be poured between these members. Thus, cement may be poured between the girdle members I0 and the structures II to form the girdle beams indicated in Figure 5 at l3, and also, cement may be poured between adjacent members H to form cross beams indicated at M in Figure 5.

In order to effect the pouring of the cement and retain it in its position between the various members I I and H), the flanges of such members are connected by cross ties l5, Whereon rests bottom flange members [6. Thus, the ties I5 are merely temporary ties, so that after the cementis poured, the ties I5 can be removed and the bottoms 16 can likewise be removed. It will be observed that each of the tie members l5 has upwardly and inwardly bent ends so that these tie members not only prevent spreading of the members I0 and II but are, by engagement with the lower flanges of these members, themselves supported to in turn support the bottom members l6 without the necessity of using bolts or other like f-astenings.

It will be observed from Figure 1 that the individual element ll may be expanded as shown in full lines or contracted as shown in dotted lines so that these members may be arranged to accommodate any particular size or arrangement of building that may be desired.

In the construction of the separate panels formed by the members H, these members H are spaced by wooden cross bars I! in order that a suitable plate or covering may be applied to cover each panel, the upper flanges of the panels being connected by tie bars I. It is to be understood that the tie bars l5 and I5 are so arranged that they are yield-able under pressure and may be disconnected from the flanges of the respective members l2 and it. Thus, when the mold is set up, there is provided around the building an outer trough to receive the outer beams of the building, and also there is provided a series of transverse troughs to receive the transverse beams of the building. Furthermore, the panels ii are each cover-ed at the top to receive the floor of the building. As shown in Figure 5, the covering for each panel is indicatedat 19, and when the floor is poured, it is poured above this panel Hi. It is to be understood that the floor may be made entirely of cement or either of cement combined with a supporting web of insulating material so constructed and arranged as to insulate from fire, sound and heat, or in any other manner preferred.

Between each pair of floors there is provided a series of posts 20. These posts preferably have reinforcing rods 2| therein, and also, it is further to be noted that the floor beams likewise have reinforcing rods 22 disposed therein. In addition to all this, the floor itself is preferably provided with the usual meshed reinforcing23 which is shown best in Figure 6.

In the forming of the posts described above, it is preferable to form a number of these posts at the same time. In Figure 11' there is provided a series of slightly trough-shaped members 24- which are spaced so that other members 25 may rest thereon, some of the members being provided with notches 26 to receive rods 2'! which support the members 25. The side walls of the members 24 flare outwardly while the side walls of the members 25 flare inwardly. These'membersare all timely spaced, as best shown in Figure 11, so that there is provided a hexagonal space for the reception of a hexagonal portion 28- of cement extending along the members 24 and through which rein-forcing members 2T pass. Thus, a number of the vertical posts may be made at the same time simply by filling the spaces as shown in Figure 11. Then these molds are separated, as at 29, in Figure in order that the several columns are left separate and may be set up as shown in Figure 12 with the column there indicated at 28 and the reinforcing indicated at 21 as projecting from the column, whereby the side wall portions 3i! may be attached to the column.

In the operation of the device, after the foundation has been laid, a certain number of the columns-are erected on this foundation, as clearly shown in Figure l, and the inner and outer molds are assembled as also shown in that figure. Then the *panel units are covered as previously described andthe cement poured; Of course the necessary reinforcing will be inserted wherever desired during this operation. When these parts have all been poured, then the story from the foundation to the first floor will have been made. After this has been done, the mold may be removed by first removing the members l5 and i5 by bending out their ends to leave the remaining parts free. After this, the members I! may be removed by angular displacement within the frames '5 I, whereupon the latter may be collapsed telescopically and dropped. Then the operation may be started all over by again assembling the columns 20 above the lower columns 20 and replacing the mold devices as before stated.

Obviously, it may be necessary, in some cases, to provide wooden supports for the panel between the mold members, but nevertheless these wooden supports can be used repeatedly without injury.

From the foregoing construction, it will be seen that all of the mold members used in this device can be used repeatedly and that there will be no injury to any one of them except such as may occur by improper handling. In other words, these mold members will form mold members which can be taken from one building to another and accommodated to any size of bull-ding with any sizes of door panels and any number or arrangement of cross beams.

There has thus been provided a simple and efficient device for accomplishing the entire molding of a building in accordance with the present invention.

It is obvious that changes may be made in'the form and construction of these molds and the various arrangements of parts without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is desired to include all forms which properly come within the scope of the appended claims.
